我們常看到的(de)一(yi)(yi)些3C產品(pin)，里(li)面都有(you)(you)安(an)裝鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)具有(you)(you)高(gao)(gao)能量密度、高(gao)(gao)電(dian)(dian)(dian)(dian)(dian)壓、壽命長、無記(ji)憶(yi)效應等(deng)優點，是(shi)21世紀發(fa)展的(de)理想電(dian)(dian)(dian)(dian)(dian)源。鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)可廣泛應用于 3C 也被稱(cheng)為手機、平板電(dian)(dian)(dian)(dian)(dian)腦、筆記(ji)本電(dian)(dian)(dian)(dian)(dian)腦、可穿戴設備(bei)等(deng)領域(yu)3C鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)3C鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)容(rong)易因短路、過(guo)充等(deng)原因燒毀或爆炸(zha)，所以很危險3C鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)測(ce)試(shi)是(shi)鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)制造和組裝的(de)重要(yao)環節，是(shi)實現鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)性(xing)能和安(an)全靠譜使(shi)用的(de)有(you)(you)力保障，3C鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)測(ce)試(shi)項目主要(yao)包括一(yi)(yi)致性(xing)、功能性(xing)、安(an)全性(xing)、靠譜性(xing)和工(gong)況模(mo)擬。

　　3C鋰電池(chi)(chi)測(ce)(ce)試(shi)對電池(chi)(chi)測(ce)(ce)試(shi)模(mo)塊的(de)選擇(ze)很(hen)重(zhong)要。目前市場上廣泛使用的(de)電池(chi)(chi)測(ce)(ce)試(shi)模(mo)塊有兩種(zhong)，一種(zhong)是(shi)凱(kai)智通(tong)(tong)大電流(liu)彈片微(wei)針模(mo)塊，另一種(zhong)是(shi)pogo pin探針模(mo)塊。通(tong)(tong)過比較兩者的(de)優(you)缺點，我們可(ke)以(yi)更直觀地(di)區分哪一個(ge)更符合(he)要求3C鋰電池(chi)(chi)測(ce)(ce)試(shi)要求。

　　從目前的市場趨勢來看，3C電子產品內部空間集成度高，pitch不斷縮小，日韓三級:pogopin探針模塊小pitch該領域適應性差，只能處理0.3mm-0.4mm之間的pitch壽命和穩定性差。3C鋰電池測試對電流的需求很大，pogopin探針模塊能承載的額定電流僅為1A，在傳輸過程中，電流會在不同位衰減，導致連接不穩定。

　　無論(lun)面(mian)對小間距還(huan)是(shi)大(da)(da)電(dian)(dian)(dian)(dian)流(liu)(liu)，大(da)(da)電(dian)(dian)(dian)(dian)流(liu)(liu)彈片(pian)(pian)微(wei)針(zhen)(zhen)模塊都有(you)很(hen)好的(de)(de)應對方法(fa)。pitch在該領(ling)域，大(da)(da)電(dian)(dian)(dian)(dian)流(liu)(liu)彈片(pian)(pian)微(wei)針(zhen)(zhen)模塊是(shi)可取的(de)(de)pitch值在0.15mm-0.4mm性能穩(wen)定(ding)(ding)(ding)靠(kao)譜。面(mian)對大(da)(da)電(dian)(dian)(dian)(dian)流(liu)(liu)測(ce)試(shi)要求，大(da)(da)電(dian)(dian)(dian)(dian)流(liu)(liu)彈片(pian)(pian)微(wei)針(zhen)(zhen)模塊可通過的(de)(de)額定(ding)(ding)(ding)電(dian)(dian)(dian)(dian)流(liu)(liu)大(da)(da)到(dao)50A，在1-50A電(dian)(dian)(dian)(dian)阻恒定(ding)(ding)(ding)，幾乎沒有(you)電(dian)(dian)(dian)(dian)流(liu)(liu)衰減(jian)，具(ju)有(you)良(liang)好的(de)(de)連接(jie)功能，可以很(hen)大(da)(da)限度地保障3C鋰電(dian)(dian)(dian)(dian)池(chi)測(ce)試(shi)的(de)(de)穩(wen)定(ding)(ding)(ding)性。

　　就使用壽(shou)命(ming)(ming)而言(yan)，pogopin探(tan)(tan)針模(mo)塊(kuai)的試驗壽(shou)命(ming)(ming)在于5w大(da)電流(liu)(liu)彈片(pian)微針模(mo)塊(kuai)的試驗壽(shou)命(ming)(ming)約為(wei)(wei)20w以上，比(bi)(bi)較pogopin探(tan)(tan)針模(mo)塊(kuai)整(zheng)整(zheng)多了四(si)倍！pogopin探(tan)(tan)針模(mo)塊(kuai)為(wei)(wei)多組件結構，生(sheng)產工藝復雜，生(sheng)產難(nan)度(du)高，交貨周(zhou)期(qi)長；大(da)型電流(liu)(liu)彈片(pian)微針模(mo)塊(kuai)為(wei)(wei)一體化彈片(pian)結構，輕、扁(bian)平，可根據客(ke)戶要求(qiu)定制，生(sheng)產難(nan)度(du)低，交貨周(zhou)期(qi)短。相比(bi)(bi)之下，大(da)型電流(liu)(liu)彈片(pian)微針模(mo)塊(kuai)的成本性能(neng)并(bing)不太高！

　　對(dui)比母(mu)座(zuo)測試良率，pogopin探針模(mo)組針對(dui)BTB連接(jie)(jie)器母(mu)座(zuo)幾乎(hu)無法(fa)實現(xian)，穩定性極差。大(da)部分采用觸摸方(fang)案對(dui)應(ying)，母(mu)座(zuo)測試良率不到80%；母(mu)座(zuo)上有一種特別的大(da)電流(liu)彈片微針模(mo)塊對(dui)應(ying)方(fang)法(fa)。將斜口型（也(ye)稱尖(jian)頭(tou)型）彈片頭(tou)插(cha)入連接(jie)(jie)器內(nei)端子，以(yi)保持一定的開度，從而保障彈片的接(jie)(jie)觸面(mian)和接(jie)(jie)觸面(mian)BTB連接(jie)(jie)器端子兩側保持接(jie)(jie)觸狀態，使測試穩定，母(mu)座(zuo)測試良率高達99.8%。

　
　大電流彈片微針(zhen)模塊測試(shi)效率(lv)高，穩定性好(hao)。與同一產(chan)品測試(shi)前后相(xiang)比(bi)，連接器基本上看不到刺痕，不會對產(chan)品造成任何損(sun)壞pogopin探針(zhen)電池測試(shi)模塊更值(zhi)得(de)選擇和信賴(lai)。
